us to stop playing tricks with sizeof(md_ioctl32)+y as well as
simplifies md_pad handling. Both were necessary because of different

illumos 4185 ("add new cryptographic checksums to ZFS: SHA-512,

without adding support for skein, sha512 and edonr on FreeBSD.

Support for skein and sha512 was added later on, but edonr is still not
implemented in FreeBSD.

Prior to this commit zfs(8) correctly rejected edonr, but with an error
message that claimed support:

cannot set property for 'tank': 'checksum' must be one of 'on | off | fletcher2 | fletcher4 | sha256 | sha512 | skein | edonr'

9f8ed7e40b Fix NVMe's use of XPT_GDEV_TYPE
This patch changes the way XPT_GDEV_TYPE works for NVMe. The current
ccb_getdev structure includes pointers to the NVMe Identify Controller
and Namespace structures, but these are kernel virtual addresses which
are not accessible from user space.

As an alternative, the patch changes the pointers into padding in
ccb_getdev and adds two new types to ccb_dev_advinfo to retrieve the
Identify Controller (CDAI_TYPE_NVME_CNTRL) and Namespace
(CDAI_TYPE_NVME_NS) data structures.

2744a0b69b Drop CACHE_LINE_SIZE to 64 bytes on x86
The actual cache line size has always been 64 bytes.

The 128 number arose as an optimization for Core 2 era Intel processors.  By
default (configurable in BIOS), these CPUs would prefetch adjacent cache
lines unintelligently.  Newer CPUs prefetch more intelligently.

The latest Core 2 era CPU was introduced in September 2008 (Xeon 7400
series, "Dunnington").  If you are still using one of these CPUs, especially
in a multi-socket configuration, consider locating the "adjacent cache line
prefetch" option in BIOS and disabling it.

aed9aaaa76 Synchronize page laundering with pmap_extract_and_hold().
Before r207410, the hold count of a page in a page queue was protected
by the queue lock, and, before laundering a page, the page daemon
removed managed writeable mappings of the page before releasing the
queue lock. This ensured that other threads could not concurrently
create transient writeable mappings using pmap_extract_and_hold() on a
user map, as is done for example by vmapbuf(). With that revision,
however, a race can allow the creation of such a mapping, meaning that
the page might be modified as it is being laundered, potentially
resulting in it being marked clean when its contents do not match
those given to the pager. Close the race by using the page lock to
synchronize the hold count check in vm_pageout_cluster() with the
removal of writeable managed mappings.

8359a6b7b3 Allow vdrop() of a vnode not yet on the per-mount list after r306512.
The old code allowed calling vdrop() before insmntque() to place the vnode back
onto the freelist for later recycling.  Some downstream consumers may rely on
this support.  Normally insmntque() failing is fine since is uses vgone() and
immediately frees the vnode rather than attempting to add it to the freelist if
vdrop() were used instead.

Also assert that vhold() cannot be used on such a vnode.

d5efa0a475 Switching from a global hash table to per-vm_object radix tries for mapping
vm_object page indices to on-disk swap space (r322913) has changed the
synchronization requirements for a couple swap pager functions.  Whereas
before a read lock on the vm object sufficed because of the global mutex
on the hash table, a write lock on the vm object may now be required.  In
particular, calls to vm_pager_page_unswapped() now require a write lock on
the vm_object.  Consequently, vm_fault()'s fast path cannot call
vm_pager_page_unswapped().  The swap space will have to be released at a
later point.
